Question

The ratio of magnetic potentials due to magnetic dipole in the end-on position to that in the broad side on position for the same distance from it is –

• A. Zero
• B. 1
• C. 2
• D. ∞

Answer 1

Answer: (D)

∞

Answer 2

V = $\frac { K M \cos \theta } { r ^ { 2 } }$ , V_axis = Q θ = 0

V_equator = 0 Q θ = 90⁰ ⇒ $\frac { \mathrm { V } _ { \text {axis } } } { \mathrm { V } _ { \text {equator } } }$ = ∞
